sal eyes. The sides are nearly vertical at the anterior end, but 

 in the thoracic part they round outward. The quadrangle of 

 the eyes is one-fourth wider than long, and a very little wider 

 in front than behind. It occupies two-fifths of the cephalo- 

 thorax. The first row of eyes is slightly curved downward, 

 that is, the tops of the middle eyes are slightly higher than the 

 tops of the lateral eyes. They are all close together, the middle 

 being two-and-one-half times as large as the lateral. The sec- 

 ond row is nearer the first than the third. The third row is 

 not so wide as the cephalothorax at that place. 



The clypeus is narrow. The falces of the male are oblique- 

 ly directed forward ; they are rather long and stout, with a 

 long fang. Those of the female are short and vertical. The 

 sternum is wide (wider in the male than in the female) and 

 rounded. The maxilla' are rounded and are twice as long as 

 the labium. 



In the male the cephalothorax is dark reddish-brown. 

 On the upper anterior part is a region which extends a little 

 back of the dorsal eyes, narrowing behind, which is of a bright 

 gold color. Crossing this region, in front of the dorsal eyes, is 

 a dark brown band, which is sometimes concentrated into two 

 black spots. The hairs around the anterior eyes are yellow. 

 On each upper side, just below the eyes, is a narrow band of 

 white hairs extending a little farther back than the dorsal eyes. 

 The abdomen is brown. Around the sides and anterior end 

 runs a narrow baiid of white hairs. Across the dorsum are 

 four curved bands, or transversely elongated spots, of a darker 

 brown. The drawing represents the spider as it appears under 

 alcohol. The space between the bands was probably originally 

 covered with white hairs. The clj'peus is covered with white 

 hairs. The falces are bright brown. The first and second 

 legs and the palpi are dark brown ; the third and fourth legs 

 reddish-yellow, with the femoral joints dark brown. 



In the female the cephalothorax is bright reddish-yellow. 

 The eye region is gold color, with two central black spots, from 

 which spring, in one specimen, some tufts of black hairs. The 

 eyes are on black spots. There are some yellow hairs on the
